Struct Dialogs 

pub struct Dialogs<T> {
    shower: Rc<dyn ShowDialog>,
    waker: Arc<dyn Waker>,
    asked: RefCell<Vec<(FileDialog, T)>>,
    answers: Rc<RefCell<VecDeque<(T, Picked)>>>,
}

The dialogs an app has asked for, and the answers that have come back. T says where each answer goes, in whatever terms the app uses.

Fields

shower: Rc<dyn ShowDialog>

waker: Arc<dyn Waker>

asked: RefCell<Vec<(FileDialog, T)>>

answers: Rc<RefCell<VecDeque<(T, Picked)>>>

Implementations

impl<T: 'static> Dialogs<T>

pub fn new(shower: Rc<dyn ShowDialog>, waker: Arc<dyn Waker>) -> Self

waker asks the UI thread to call Dialogs::show_asked and then, inside an event, Dialogs::receive.

pub fn ask(&self, dialog: FileDialog, target: T)

Asks for dialog, to be shown once the current event has finished.

pub fn show_asked(&self)

Shows every dialog asked for since the last call. Call it from the waker’s handler outside any event: a platform may run a modal loop here, which handles other events.

pub fn receive<E>( &self, apply: impl FnMut(&T, Picked) -> Result<(), E>, ) -> Result<(), E>

Hands each answer that has come back to apply with where it goes. Stops at the first error, leaving later answers queued.

Errors

The first error apply returns.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
